1. Introduction Network equipment sometimes "locks-up", making it impossible to communicate. In the past, this situation required a trip to the installation site, simply to flip the power switch off and then back on again. When a distant installation site makes this trip costly or time consuming, the RPS-10 can do it for you! The RPS-10 allows you to remotely switch devices using simple ASCII commands sent via modem or cable.
2. Unit Description 2.1. Front Panel Figure 1: Front Panel À AC ON: Lights when power to the Switched Outlet is ON. Á LINK: Flashes when command data is received. Â RDY: Lights when AC Power is applied and the module is ready to receive commands. Does not indicate the ON/OFF condition of the Switched Outlet. 2.2. Back Panel The back panel for each RPS-10 model differs slightly as shown in Figures 2 and 3. Individual back panel components are described in detail in Section 2.3. 2.2.1.

3. Installation The installation procedure consists of the steps listed below. For more information, please refer to the section(s) indicated. 1. Set the Address for each module (Section 3.1). 2. Configure the Set-Up Switches (Section 3.2). 3. Use RJ11 Cables to link RPS-10 Modules (Section 3.3). Caution: Do not connect the Link Ports to a telephone circuit. 4. Connect your modem or local PC to the control port on the back panel of the RPS-10M Master Module (Section 3.4). 5.
RPS-10 Series Remote Power Switches, User's Guide Installation 3.2. Set-Up Switches Prior to connecting AC power to the RPS-10 Modules, configure the Set-Up Switches on each module according to the requirements of your application. Switch Function Up Down 1 Data Rate 2400 bps 9600 bps 2 Toggle Delay 10 Sec. 5 Sec.
RPS-10 Series Remote Power Switches, User's Guide Installation 3.3. Linking Modules Connect straight wired RJ11 cables between the Link Ports to link the RPS-10 Master Module and Satellite Modules as shown in Figure 4 below. • • • • Note: Use straight wired RJ11 cable to link RPS-10 Modules. Do not use cross-wired telephone cable. The total length of cabling between the first module in the link and the last module in the link cannot exceed 2,000 feet.
RPS-10 Series Remote Power Switches, User's Guide Installation Figure 5: RS232 Interface Schematic 3.4. Control Port Connection The RS232 Control Port is a male, DB9 connector, used for connection to a PC or external modem. The Control Port employs a DTE configuration, similar to an AT computer. WTI offers a complete selection of Snap Adapters to simplify connection to your PC or modem. Please refer to Section 4.1.2 for more information on RJ11 modular adapters. 3.4.1.
RPS-10 Series Remote Power Switches, User's Guide Installation 3.6. Test for Proper Installation After installation, the following test should be performed to make certain all modules are operating correctly. 1. Establish a connection with the RPS-10M Master Module. a) Via Modem: Start your terminal emulation software, and dial the number for the modem connected to the Master Module.
4. Operation Each RPS-10 module can be switched or toggled by an ASCII command string sent to the Master Module control port. The Control Device must send ASCII characters at the same data rate as the RPS-10 Module(s). The RPS-10 will accept any parity, but will always answer back at 8 bits, no parity. The command string consists of nine contiguous characters. The first six characters are ASCII control codes. These six characters constitute a "fixed password" that restricts access to the RPS-10.
RPS-10 Series Remote Power Switches, User's Guide Operation Examples: To toggle the Switched AC Outlet on the RPS-10 Module at Address "3", send the following command: ^B^X^X^B^X^X3T^M To set the Switched Outlet on the RPS-10 Module at Address "4" to the Off position, send the following command: ^B^X^X^B^X^X40^M To display the status of all linked RPS-10 Modules, send the following command: ^B^X^X^B^X^X*?^M Note: • After executing each command, the RPS-10 will send a "COMPLETE" message.
RPS-10 Series Remote Power Switches, User's Guide Operation 4.1. Optional Accessories 4.1.1. Three Module Rack WTI offers an optional three module rack, which fits most standard instrument racks. To assemble the rack, refer to Figure 6 and proceed as follows: 1. Remove rubber feet from bottom of each module. 2. Attach right bracket (4) to rack tray (6) using two black, Phillips head screws (3) supplied. Repeat step for left bracket (7). 3. Place three modules (1) in rack tray (6).
RPS-10 Series Remote Power Switches, User's Guide Operation 4.1.2. Snap Adapters WTI offers a complete selection of snap adapters and cables designed to simplify connection between the RPS-10M Master Module and your Modem or PC. These snap adapters and cables are described in the table below and in Figure 7. WTI Part No. Description SA-28F DB9 to RJ11 Adapter AC-LL Straight Wired RJ11 Cable (LL = Length, 10 to 150 ft.
